where to buy clutch spring

[Dutchman]

My 13 Pro RMK 600 uses a blk/grn primary spring, part #7042083.
Is the OEM the best option or is there an aftermarket to match up, and where to buy?

I have a 600 155 as well and I switched to the SLP Blue/Pink spring. Little stiffer and gives me an extra 50 Rpm $25 from cycle works.

We've got both here, blue/pink SLP has been working great, $27.99 and the stock polaris spring is $49.99
